IPC: H03B5/04
Filed: 1978-10-17
Abstract: PURPOSE: To enhance the temperature stability of the oscillator by placing the dielectric resonator directly on the earth conductor or case metal to be then combined to the microstrip line.  
     CONSTITUTION: Teflon substrate 20 beside the microstrip line consisting of strip conductor 21 and earth conductor 22 on the upper and rear surfaces of substrate 20 is cut out along the line, and dielectric resonator 23 is fixed on conductor 22 or motal case plate 24 to be combined to the microstrip line. In such way, the resonation frequency of resonator 23 can be set regardless of the linear expansion coefficient of the Teflon, thus enhancing the temperature stability. Also a hole is drilled on substrate 20 instead of cutting out partially, and resonator 23 is fixed to conductor 22 or the like to obtain the same effect.

Title: Manufacture of optical disk, optical disk and optical disk device
Inventor: KOBAYASHI SHOEI
IPC: G11B7/1374
Filed: 1997-05-19
Abstract: PROBLEM TO BE SOLVED: To form a groove by generating a wobble signal by a phase modulation and meandering a groove thereby generating wobble signal while using a single carrier frequency. SOLUTION: After a wobble signal generating circuit 7 performs the biphase modulation of wobble data ADIP, the circuit 7 generates the signal subjected to a phase modulation by a single carrier frequency by inserting synchronous patterns in between the wobble data and outputs this signal subjected to the phase modulation as a wobble signal. In an optical disk, the snaking cycle of the groove which is converted into the rotational angle of the optical disk is formed constantly by rotatingly driving a master disk 2 in the condition of a constant angular velocity and by forming the groove by the signal subjected to the phase modulation. Respective edge information of edge information to be obtained by being binarized have correct phase information and a highly accurate write and read clock is generated by being synchronized with phases of the edge information.

Inventor: TSURU SEIJI
IPC: F04C23/00
Filed: 1986-06-04
Abstract: PURPOSE:To make a motor small-sized by starting a pump of a latter stage and starting a pump of a former stage after a back pressure or a suction pressure of the pump of the former stage drops to or below a set pressure. CONSTITUTION:Starting a pump 20 of a latter stage by means of a motor 22, gas in a pump 19 of a former stage and in a chamber 21 to be exhausted is discharged to reduce its pressures. When the pressure in the chamber 21 to be exhausted decreases to or below a set pressure, a pressure switch 26 works to engage a solenoid clutch 27 and to start the former stage pump 19. Since the suction pressure and back pressure of the former stage pump 19 have been decreased, it can be started with a small torque and therefore the motor can be made small-sized.

Abstract: PURPOSE:To improve the sensitivity of the detection of a contaminated part on the surface of a semiconductor wafer or a defective which is present locally by performing the synchronous phase detection of an AC light voltage in the semiconductor wafer surface and subtracting a DC component contained in the distribution of a light voltage with an effective value. CONSTITUTION:When light which becomes intermittent light of frequency through brightness modulation is projected on the semiconductor wafer 14, the AC light voltage is generated. This voltage can be detected by the electrostatic capacity consisting of the wafer 14 and a transparent electrode 15 without forming any electrode on the wafer 14. The detected AC light voltage is controlled to the effective value of the AC voltage of a synchronous phase detector 24 and inputted to a signal processing circuit 6. The signal after the contrast is emphasized by this circuit 6 is A/D-converted 7 and stored in a frame memory 9 through the interface circuit 8 of a microcomputer 12. The light spot of a CRT 18, on the other hand, is scanned at a spot position by the deflecting coil 19 of a deflection driving circuit 21 according to a signal from an oscillator 23. Consequently, information in the plane of a wafer 14 is stored in a memory 9 and this information is displayed 11 through a scan converter 10 to obtain a light voltage distribution image.

IPC: F28D5/02
Filed: 1987-05-27
Abstract: PURPOSE:To increase an efficiency of thermal conduction and promote an evaporation by a method wherein fluid flowing down in a thin film form within inverted V-shaped elements with fluid flowing in V-shaped spaces formed between the inverted V-shaped plates is heated and evaporated. CONSTITUTION:Plates where processed fluid is flowed down are made inverted V-shape, a plurality of elements 1-1 forming a cylindrical passage are arranged side-by-side and a blind plate 1-6 is provided in order to prevent a mixing of two fluids. The brine 1-3 supplied by a distributer 1-2 is flowed down on an inverted V-shaped slant surface of V-element 1-1 as a uniform thin film liquid. In turn, heating fluid 1-4 supplied into the V-element 1-1 may heat the thin film liquid through plates of the V-element 1-1 to generate steam 1-5. Non- evaporated brine 1-3 is flowed out of a clearance between the V-elements. Therefore, an increasing of volume or decreasing of volume accompanying a variation in phase from brine to vapor shows a variation in section and so a non-uniform flow or a liquid closing can be eliminated.

Abstract: PURPOSE: To improve characteristics of a tube, by forming frame-mask parts, provided facing to a fluorescent screen formed on an internal bulb surface, through the welding fabrication of a mild steel part thermally oxidized after Ni plating to a thickness of 0.5 to 3.0μm.  
     CONSTITUTION: The surface of mask frame 2 of mild steel supporting shadow mask 1 is plated with Ni to a thickness of 0.5 to 3.0μm and then blackened, where shadow mask 1 is welded and fixed afterward. Next, mask 1 is fitted to the front surface of panel 4 after prescribed processes. In this method, welding is simplified, and the breakaway of the coating and splash both lessen extremely. Here, the recommendable thickness of Ni plating is between 1.0 and 1.5μm; a thinner coating lessens the effect of Ni plating and a thicker one makes hard the formation of the coating during an oxidation process to the contrary.
